For best ev spread, you’ll want to max out the best 2 stats and 4 extra ev into the 3rd best. This won’t always be the case as some Pokémon may require specific ev spreads. To get a good base line idea, check out smogon’s website, they list every single Pokémon on how viable they are in competitive battling. You should be able to get the right ev spread using that website.
